PUMPING EQUIPMENT" FOR WELLS.

Application filed NovemberlG, 1923. Serial No. 675,164.

To all whom t may concern:

Be it known that we, Tillmann B. PINE and IRA V. MARTIN, citizens of theUnited States of America, and residents of Okmulgee, in the county ofOkmulgee, State of klahoma, have invented certain new and usefulImprovements in Pumping Equip-- ment for l/Vells, of which the followingis a specification.

This invention relates to pumping equipment especially adapted for usein oil wells.

Briefly stated, an important object of this invention is to provide aworking ha. rel having` reliable means to prevent floating sand fromsettling on the packers and rapidly wearing the same.

A further object is to provide a working barrel having novel meanswhereby to trap the sand upon being directed away from the packerssothat it cannot again be picked up by the fiuid. f

A further object is to provide a pumping equipment which is simple tooperate7 reliable in use and one in which the necessity for yfrequentlypulling the tubing is overcome.

Other objects and advantages will be an parent during the course of thefollowing description.

ln the accompanying drawing forming a part of this application and inwhich like numerals are employed throughout the same,

Figure 1 is a vertical sectional view through the improved pumpingequipment.

Figure 2 is a horizontal sectional view taken on line 2-2 of Figure 1.

Figure 3 is a detail section illustrating the plunger about to enter thesand deflector.

ln the drawing wherein for the purpose of illustration is shown apreferred embodiment of the invention the numeral 5 designates a tubing,the lower portion of which is threaded into an upper bushing G, the saidbushing formingI what might be said to be the head of the workingbarrel.

As illust-rated in Figure l, a tubular housing 7 is threaded onto thelower portion of the bushing 6 and has connection with a lower bushing8. An inner housing 9 consistituting the working barrel is threaded intothe lower bushing 8 and supports at its upper end a hydraulic packing10, the

said packing being mounted on the upper end of an inner bushing 11 andbeing confined within a tubular stufhng box 12.

ln carrying out the invention a plunger 14 is slidable through thepacking` 12 and is provided ,at its upper end with a caged valve Ofcourse on the upward stroke of the plunger 14 thevvalve 15 is seated andon the down stroke of the plunger the valvel is unseated so as to allowthe fluid to enter the tubing 5. i

Attention is directed to the fact that an exteriorly tapered sanddeflector and scraper. 18" is mounted on the upper end of the packing 12and receives the plunger 111 so that any sand on the plunger iseffectively scraped from the same and directed through a plurality ofvertical slots 19 in the adjacent portion of the packing box 12. lt willbe seen that the lower portion of the plunger 1&1 is exteriorly taperedas indicated at 20 so that when the same is lowered it will freely passthrough the combined sand deflector and scraper. Also, the plunger 1stis guided by the upper bushing 6 and is held in longitudinal alignmentwith the member 18 so that the plunger will freely enter the workingbarrel. By reason of this 'construction it islpossible to remove theplunger for repair or replacement withf out pulling the tubing, avfeature very valuable to the inventon.

The usual standing valve 25 is lmounted within the inner housing 9 asuitable distance above the lower end of the housing and is supported bymeans of an inlet pipe 26.

lnoperation the plunger is reciprocated and any floating sand whichsettles is directed through the slots 19 into the annular sand trapdefined by the inner and outer housings and the tubular stuffing box.Figure 1 illustrates that the upper end of the combined scraper anddeflector tapers to a knife like edge so as to thoroughly scrape allsand from the plunger and thereby prevent the sand from settling on thepacker.

The sand cannot remain within the upper portion of the packing box asthe slots extend a substantial distance below the tapered portion of thesand deflector. Therefore, no pockets are formed within the packing box.

Replacement or repairs to the tubing cartied elements of the inventionmay be com i l i l veniently made by pulling` the tubing to the surfaceand the sand may also be removed from the sand trap by pulling thetubing.

It is believed to be obvious that the working barrel is supported asuitable distance above the bottom of the well by a main inlet member28, the lower portion of which may be perforated.

Having thus described the invention, what is claimed is l l. A pumpingequipment comprising a housing, a packing box arranged within thehousing and having slots establishing communication 'between theinterior of the box and the interior of the housing, a plunger movablethrough the packing box, a barrel receiving .said plunger, a packingcarried by the box and surrounding the plunger, and a sand deiieetormounted on the packing and directing settling sand through said slots.

2. A pumping equipment comprising a housing having a sand trap, apacking box having slots establishing communication. between theinterior of the box and said sand trap, a packing arranged in said box,a plunger movable through said packing, and a barrel receiving saidplunger.

3. A pumping' equipment comprising a housing having a sand trap, apacking box having slots establishing communication between the interiorof the box and said sand trap, a packing arranged in said box, a plungermovable through said packing, a barrel receiving said plunger, and acombined plunger scraper and sand deilector arranged within said boxinwardly of said slots.

i. A pumping equipment comprising a. housing having a sand trap, apac-king box having slots establishing communication be-1 tween theinterior oit the box and said sand trap, a packing arranged in said box,a plunger movable through said packing, a barrel receiving said plunger,a combined plunger scraper and sand deHec-tor arranged within said boxinwardly of said slots, and a bushing connected to said housing andreceiving and guiding said plunger.

5. A pumping equipment comprising a housing having a sand trap, apacking box having slots establishing communication between the interiorof the box and said sand trap, a packing arranged in said box, a plungermovable through said packing, a barrel receiving said plunger, acombined plunger scraper and sand detlector arranged within said boxinwardly of said slots, and

a standing valve arranged in said barreh` the upper portion of saitLscraper and deflector being tapered to a knife-like edge.

6. A pumping equipment comprising housing having a sand trap, a packingbox iaving slots establishing communication between the interior of thebox and said sand trap, a packing arranged in said box, a plungermovable through said packing, a barrel receiving said plunger, and acombined plunger scraper and sand deilector arranged within said box,inwardly of said slots, said scraper and deliector being exteriorlytapered for directing sand through said slots, the lower portions ofsaid slots being located below the tapered portion of said scraper anddeflector.

7. A pumping equipment comprising a housing having a sand trap, apacking box connected with the housing having slots af'- fordingcommunication between the interior of the box and said sand trap, apacking arranged in said box, a plunger movable through said packing, abarrel arranged within the housing, said barrel being connected with thepacking box and being arranged to receive said plunger, and a combinedplunger scraper and sand def-lector arranged within said box above thepacking andY inwardly of said slots.
